Volcano Calendar 2019: We're proud to present our 2019 volcano calendar: 13 different and attractive images of volcanoes, volcanic landscapes and phenomena taken during volcano tours over the past few years.

The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.

In this photo released by the civil defense unit of the state government of Jalisco, the eruption plume from the initial stage of the powerful vulcanian explosion at Colima volcano on May 23, 2005, has been captured on film. The collapsing eruption column loaded with ash and rock fragments has not yet fully developed, but the flanks of the volcano are already covered by the impacts of ballistics.

Colima volcano is one of the most active volcanoes in North America and one of the potentially most dangerous ones. It has had more than 30 periods of eruptions since 1585, including several significant eruptions in the late 1990s. Scientific monitoring of the volcano began 20 years ago.

Colima volcano (Mexico): increased activity, lava flows

Activity has increased recently, judging from recent pcitures of the volcano. Abundant rockfalls and lava flows descend the flank of the steep cone. It appears that growth of the lava dome has resumed in speed and overflows the rims of the crater.

Explosions, rockfalls and small pyroclastic flows, as well as volcanic earthquakes have increased and become more frequent at the volcano. Hot pyroclastic deposits on the eastern flank of the volcano are visible on recent MODIS satellite image data. [more]

The new lava dome continues to grow inside the crater that had formed during the eruptions in January and has by now been completely filled by the new lava. The dome overspills the old crater rims to the southerns and western sides and produces glowing avalanches as well as small ash explosions several times per hour. ... [more]

Background:

Colima volcano is one of the most active in North America and one of the potentially most dangerous ones. It has had more than 30 periods of eruptions since 1585, including several significant eruptions in the late 1990s. Scientific monitoring of the volcano began 20 years ago.

The Colima volcanic complex is the most prominent volcanic center of the western Mexican Volcanic Belt. It consists of two southward-younging volcanoes, Nevado de Colima (the 4320 m high point of the complex) on the north and the 3850-m-high historically active Volcán de Colima at the south.
A group of cinder cones of probable late-Pleistocene age is located on the floor of the Colima graben west and east of the Colima complex. Volcán de Colima (also known as Volcán Fuego) is a youthful stratovolcano constructed within a 5-km-wide caldera, breached to the south, that has been the source of large debris avalanches. Major slope failures have occurred repeatedly from both the Nevado and Colima cones, and have produced a thick apron of debris-avalanche deposits on three sides of the complex. Frequent historical eruptions date back to the 16th century. Occasional major explosive eruptions (most recently in 1913) have destroyed the summit and left a deep, steep-sided crater that was slowly refilled and then overtopped by lava dome growth.

Ijen volcano photos: Ijen volcano in East Java is famous for its turquoise acid crater lake and the large sulfur deposits that are being mined by local workers. At night, the scene is illuminated by ghostly blue flames, as sulfur ignites.
